Page 246 Respiration is studied in biological science, but the mechanics of breathing are governed by the laws of physical science. What are these laws? What other phenomena do they describe in the natural world and in technology?
A short, easy explanation of Dalton's law, using scuba diving as example. This is a Java-based site, requiring Shockwave to view
animations. (

This site offers an animated or a slide and text version of Boyle's Law. It includes links to definitions of pressure, temperature and
volume of gases, as well as further information on properties of gases. There is easy navigation to activities on Boyle's Law, which are focused on learning
about propulsion, among other things. (

Page 256 Infections of the respiratory tract often have similar symptoms. How can one infection be distinguished from the other? And, more importantly, what can be done to feel better and get better when an infection sets in?
This site distinguishes between some of the most common causes of a sore throat. Sometimes it's nothing serious, and sometimes it's a sign
of something that needs medical attention. (

Page 258 ? Asthma is the only major respiratory ailment that is increasing in the population. Approximately 20 years ago, 2.3 percent of Canadians over the age of 15 were diagnosed with asthma. Today, this figure has increased to more than 8 percent. The United States has seen more than a 60 percent increase in the diagnosis of asthma. What hypotheses do medical experts have to explain these dramatic increases?
T his website outlines the latest trends and causes of asthmas and links to an article summarizing the latest hypotheses on the increase
in incidence of childhood asthma. (
